This CO2 question is so stupid I would be afraid to ask it if I had any shame. OK, so here it goes: I now have my CO2 bottle, my kegs, my quick disconnects an my faucets. All under control. But how do I use the CO2 bottle to purge bottles and fermentors?
I use one of these.

I have Kent disconnects on my lines so I can swap out accessories.
Completely, totally, absolutely, wholly, and utterly lost on all counts to the max.
Hook up your CO2 to a line with no disconnect on the end. Stick the line down inside your fermenter as far as it will go. Turn on the CO2.
I use these - Category not found!
Both regulators have a short tube with a female disconnect. I also have a 5 foot hose with male/female. I then have 1 foot lengths with a ball lock fitting, air gun/nozzle, and just plan tubing.
Same thing I’ve done in the past.
You could also have a spare keg filled with co2 and use a bottle wand stuck in a picnic tap to purge bottles.
A hose. Soak it in sanitizer first. I don’t purge anything that hasn’t been fined or cold crashed. Purging kegs is worth it.
I purge kegs occasionally such as for a beer I want to preserve the super hoppy character, but I don’t bother most of the time. I do purge the headspace immediately after filling and putting the lid on the keg, after racking the beer from the fermenter to the keg.
I just remove the QD, run a paper towel dipped in Star San up and down the gas hose and fitting, and put it down into the keg.
I’ve never purged beer bottles, but I do use o2 scouring bottle caps.
